DynamicLinks.API在此设备上不可用

Question

我已经在我的即时应用中实现了动态链接，当点击链接打开即时应用程序但是在方法getDynamicLink（意图）中它显示以下错误：

com.google.android.gms.common.api.ApiException: 17: API: DynamicLinks.API is not available on this device.

我班上的代码如下：

FirebaseDynamicLinks.getInstance()
            .getDynamicLink(intent)
            .addOnSuccessListener(this)
            {
                pendingDynamicLinkData ->
                // Get deep link from result (may be null if no link is found)
                var deepLink: Uri? = null
                if (pendingDynamicLinkData != null) {
                    deepLink = pendingDynamicLinkData.link
                }


                showAlertDialog(deepLink.toString())
                // Handle the deep link. For example, open the linked
                // content, or apply promotional credit to the user's
                // account.
                // ...

                // ...
            }
            .addOnFailureListener(this) { e -> Log.w("FailureListener", "getDynamicLink:onFailure", e) }

请帮帮我。
